Intervención educativa para perfeccionar la ejecución del Programa de Detección Precoz del Cáncer Bucal

Introducción: las lesiones premalignas y malignas del complejo bucal se incrementan en la población, lo que demanda una correcta ejecución del Programa de Detección Precoz del Cáncer Bucal (PDCB). En el trabajo se exponen las transformaciones en el nivel de conocimientos de pacientes y estomatólogos acerca de las afecciones concernientes al PDCB para perfeccionar su ejecución. Método: se realizó una intervención educativa en el área de salud Julio Antonio Mella del municipio Camagüey desde mayo de 2022 hasta junio de 2023, con la participación de 36 pacientes y 30 estomatólogos. Las fuentes de información fueron la historia clínica, un cuestionario y una prueba de entrada y salida, aplicados a pacientes y estomatólogos respectivamente, antes y después de la intervención; para constatar las transformaciones. Resultados: antes de la intervención los pacientes estaban mal informados sobre las consecuencias nocivas de hábitos tóxicos, higiénicos y dietéticos, así como desconocimiento de la importancia del correcto autoexamen bucal; los que alcanzaron en su mayoría un alto nivel de conocimientos con la intervención. Los estomatólogos mejoraron sus conocimientos sobre diagnóstico y seguimiento de lesiones pre malignas y malignas del complejo maxilofacial. Discusión: la adecuada ejecución del PDCB descansa tanto en pacientes como en estomatólogos y aunque las investigaciones se enfocan a los primeros por los beneficios reportados; la superación de posgrado constituye una vía para sistematizar conocimientos y fortalecer competencias profesionales que impacten de manera positiva en el PDCB. La intervención educativa se considera satisfactoria al elevar el nivel de conocimientos de pacientes y estomatólogos, lo que demuestra sus potencialidades para perfeccionar la ejecución del PDCB.

Introduction: premalignant and malignant lesions of de oral area increase in the population which demands a correct implementation of the Early Detection of Oral Cancer Program. In this work transformations are exposed knowledge level of both patients and dentists regarding lesions concerning the Early Detection of Oral Cancer Program (EDOCP). Method: educational intervention was carried out in Julio Antonio Mella health area of Camaguey municipality from May 2022 to June 2023 which 36 patients and 30 Deontologists. Information sources were the Clinical History, a questionnaire and a test applied to patients and Deontologists respectively, before and after the intervention, to confirm the transformations in the sample. Results: Prior to intervention patients were poorly informed about consequences of toxic, hygienic and dietetic habits combined with lack of knowledge regarding importance of a correct oral self-examination whose knowledge improved to reach a high level in most of them after the intervention. Deontologists improved their knowledge on diagnosis and follow-up of premalignant and malignant lesions affecting the maxillofacial complex. Discussion: correct application of the EDOCP depends on both patients and deontologists, however reserchers focus on the former due to the reported benefits; the postgraduate training is a way to systematize knowledge and strengthen professional competences with positive impact on EDOCP. The educational intervention was satisfactory since it improved the level of knowledge of both patients and dentists which shows its potential on a correct implementation of the Early Detection of Oral Cancer Program.

Trimethoprim-sulfamethoxazole increase micronuclei formation in peripheral blood from weanling well-nourished and malnourished rats.

The combination of trimethoprim and sulfamethoxazole (TMP-SMX) is a widely used drug. In spite of this, there are few reports on its genotoxicity, and the results are controversial. Severe malnutrition is a complex condition that increases the susceptibility to infections. Consequently, drugs are extensively used in malnutrition cases. Experimental animal models have been widely used to study the effects of malnutrition. Neonatal rats were experimentally malnourished (UN) during lactation. The UN rats weighed 51.1% less than the well-nourished (WN) controls and had lower concentrations of serum protein and blood lipids. The micronucleus (MN) assay is useful for detecting chromosome damage induced by nutritional deficiencies. In vivo rodent MN assays have been widely used to screen genotoxic agents. In this study, we have evaluated the frequency of spontaneous and TMP-SMX-induced micronuclei in the peripheral blood of weanling (21 days of age) rats using a flow cytometric analysis technique. The spontaneous frequency of micronucleated reticulocytes (MN-RETs) was 2.7 times greater in the UN rats than in the WN rats. In rats that were not treated with TMP-SMX, the percentage of reticulocytes was significantly lower (41.1%) in the UN rats than the WN controls. A therapeutic dose of TMP-SMX (80 mg/kg (TMP), 400 mg/kg (SMX) for 48 hr) increased MN-RETs in the WN and in the UN rats. The data demonstrate the genotoxic effect of this drug. The results indicate that severe protein-calorie restriction and drug treatment enhance DNA damage in rat peripheral blood reticulocytes, potentially increasing the risk of negative effects on health.

Malnutrition and gastrointestinal and respiratory infections in children: a public health problem.

Infectious disease is the major cause of morbidity and mortality in developing countries, particularly in children. Increasing evidence suggests that protein-calorie malnutrition is the underlying reason for the increased susceptibility to infections observed in these areas. Moreover, certain infectious diseases also cause malnutrition, which can result in a vicious cycle. Malnutrition and bacterial gastrointestinal and respiratory infections represent a serious public health problem. The increased incidence and severity of infections in malnourished children is largely due to the deterioration of immune function; limited production and/or diminished functional capacity of all cellular components of the immune system have been reported in malnutrition. In this review, we analyze the cyclical relationship between malnutrition, immune response dysfunction, increased susceptibility to infectious disease, and metabolic responses that further alter nutritional status. The consequences of malnutrition are diverse and included: increased susceptibility to infection, impaired child development, increased mortality rate and individuals who come to function in suboptimal ways.
